I like that it's easy for our employees who work remotely, as well has those in-house at HQ/home office locations (in US) connect easily with their clients via this program! It also helps us keep track of all hours worked per day by each employee which makes payroll processing much easier than if we were using paper timesheets only - no more having multiple spreadsheets tracking different things!! The ease of use, speed in getting things done (and being able fix problems when they arise).
It would be nice if it was possible for more than one person within our organization/company using this product at any given point throughout its lifecycle - but that's just nitpicking really! I have been extremely impressed with PDWG as we've moved into digitizing all paper-based documentation from previous years' projects so far; there are no complaints here either way :).
